A chromatogram of low ppb levels of AsH3 and PH3 is shown below:<br />

The PID has detection limits in the low ppb range for many of the hydrides and other inorganic compounds. Arsenic in water has been shown to have a detection limit of 0.075 ppb in a paper "Total and Speciated Arsenic Compounds in Water by Photoionization and Gas Chromatography/PID" to be published in "Toxic Trace Metal Remobilization & Remediation - A Geochemical Body of Work" to be published by the ACS in 2012.<br />

The use of the 9.5 eV lamp improves the specificity of the photoionization detector (PID). Low ppm levels of these compounds are shown below. The detection limits should be in the ppb range depending on the packed columns since the PID has more than adequate sensitivity.<br />

Detection limits were in the low ppb levels for arsenic to tin and sulfide compounds. Low ppm detection limits were obtained for tellurium through ammonia. <br />

An HNU model GC311 with a PID (10.2 eV). The goal was to test the HNU Systems GC 311 for the verification of Chemical Warfare (CW) agents.<br />
<br />
<br />
Materials & Methods<br />
The CW-agents investigated in this work are listed in Table 1, The standard solutions of Model compounds were prepared in Methanol by consecutive dilutions of stock solution containing 100 ug/uL in ethyl acetate. Methanol was chosen as the solvent to eliminate a large solvent peak due to the lack of a split valve in the GC311. Methanol is not ionized by the 10.2 eV lamp.<br />

The GC311 was equipped with a photoionization detector (10.2 eV) . The compounds were separated on a fused silica capillary column (phase NBW 311, 15M x 0.53 mm id x 1.5 um film thickness) . The injection volume varied from 2.5- 5uL. Injector/detector temperature was 200C and the oven temperature was 100 C for sarin, soman, tabun and mustard gas and 150C for Lewisite-3. <br />
<br />
Results and Discussion.<br />
Figures 1 & 2 show chromatograms of a standard solutions of sarin, soman, tabun and mustard gas at concentration levels of 100, 50, 4 and 1 ng. The detection limit of sarin, soman, tabun and mustard gasis about 1 ng and for mustard gas is 0.5 ng which is about 10 x better than that of the FID run at the same time. The sensitivity of the Lewisite-3 is 0.2 ng because of the 3 double bonds in that compound.<br />

The portable GC311 has been shown to be a powerful instrument for the detection of CW-agents especially for the direct analysis of air samples. The instrument can also be used for the monitoring of incinerator exhaust gases during the destruction period of CW-agents. The analyzer could be more useful for the analysis of liquid samples if a split injector were available.<br />
The GC311 is no longer in production but a new portable GC is available from PID Analyzers, the Model GC312.<br />

The PID (Model PI52) with an HNU 11.7 eV lamp compares in sensitivity with the ECD for low MW chloroalkanes. and with the FID for a number of hydrocarbons. The HNU PID with a 10.2 eV lamp is more sensitive than the FID or the PID with an 11.7 eV lamp.<br />

This remains one of the popular downloads on our website http://www.hnu.com . I remember calling this technique a “poor man’s mass spec” but the referee made me remove it. I still believe it though. Follow my blog at http://gcdetectors.blogspot.com, and http://gasanalysis.blogspot.com, #PID/FID, #photoionization, #pidanalyzers, #identification of hydrocarbons, #GC. #PID <br />
